The Jonard FS-1080 scores and rings thin-walled microduct so you can open it without touching the fiber inside.
It handles 10/8, 12/10 and 14/12 microduct with no adjustment, on duct 5 mm to 16 mm with 1.0 mm to 1.3 mm walls.

Wide jaws curl around the duct and hold it while you score, and a spring-loaded butterfly clip opens the tool to set it on the duct.
It ships with the FS-1080RB blade. For thicker walls see the FS-1416 and FS-2025.
